commit 082f2300cfa1a3d9d5221c38c5eba85d4ab98bd8 upstream.
Local random address needs to be updated before creating connection if
RPA from LE Direct Advertising Report was resolved in host. Otherwise
remote device might ignore connection request due to address mismatch.
This was affecting following qualification test cases:
GAP/CONN/SCEP/BV-03-C, GAP/CONN/GCEP/BV-05-C, GAP/CONN/DCEP/BV-05-C

We don't actually need the full rculist.h header in sched.h anymore,
we will be able to include the smaller rcupdate.h header instead.
But first update code that relied on the implicit header inclusion.

Since we need to change the implementation, stop exposing internals.
Provide kref_read() to read the current reference count; typically
used for debug messages.
Kills two anti-patterns:
atomic_read(&kref->refcount)
kref->refcount.counter

Bluetooth: Fix using the correct source address type2016-11-22T21:50:46ZJohan Hedbergjohan.hedberg@intel.com2016-11-12T15:03:07Zurn:sha1:39385cb5f3274735b03ed1f8e7ff517b02a0beed
The hci_get_route() API is used to look up local HCI devices, however
so far it has been incapable of dealing with anything else than the
public address of HCI devices. This completely breaks with LE-only HCI
devices that do not come with a public address, but use a static
random address instead.
This patch exteds the hci_get_route() API with a src_type parameter
that's used for comparing with the right address of each HCI device.

Commit 5177a83827cd ("Bluetooth: Add debugfs fields for hardware and
firmware info") introduced hci_set_hw_info() and hci_set_fw_info().
These functions use kvasprintf_const() but are not marked with a
__printf attribute. Adding such an attribute helps detecting issues
related to printf-formatting at build time.
